目前,全世界生产的所有飞机都是越来越国际化的产物。以大中型喷气客机为例,整机制造厂家只剩波音公司和空中客车两家。但参与波音、空客飞机制造和销售的各类公司有成百上千家。 据空客公司一份技术报告称,仅美国就有数百家公司提供空客飞机所需部件的20％～40％,这些公司分布在美国50个州中的35个。波音制造的飞机上也有相当比例的外国公司产品,波音767机体的30％是在美国以外生产的,原麦道MD-80的50％由澳大利亚、意大利、瑞典、日本、瑞士和中国转包生产。在新研制的波音777上,20％是日本生产的。通常,在飞机上由转包商提供的产品大到发动机,小到新材料、电气系统零件、座椅、机上厨房和地毯等。
At present, all aircraft produced worldwide are increasingly internationalized. Take large and medium-sized passenger jets as an example. The complete machine manufacturer only has two companies, Boeing and Airbus. However, there are hundreds of companies involved in the manufacture and sale of Boeing and Airbus aircraft. According to a technical report of Airbus, only the United States has hundreds of companies providing 20% to 40% of the parts needed for Airbus aircraft. These companies are distributed in 35 of the 50 US states. Boeing also manufactures a large proportion of foreign company aircraft. 30% of the Boeing 767 fuselage is produced outside the United States. 50% of the original MD-80 is subcontracted by Australia, Italy, Sweden, Japan, Switzerland and China. . In the newly developed Boeing 777, 20% is produced in Japan. In general, the products provided by subcontractors on aircraft are as large as engines, as small as new materials, electrical system parts, seats, galleys, and carpets.
